Study on the Forming and Self-repairing of Ni60A/MoS2 Composite Lubricating Film Yuncai Zhaoa Dongling Yub Department of mechanical engineering, Jingdezhen ceramic institute, Jingdezhen Jiangxi 333403, China azhaoyuncai@126.com , bydljdz@163.com Corresponding author: Tel: 86-798-8435918; E-mail address: zhaoyuncai@126.com Keywords: Plasma spraying, composite lubricating coating, forming mechanism of the lubricating film, destroying mechanism of the lubricating film(TG174.442) Abstract.
Ceramic material tends to be elastic contact.
When the press head slips on the ceramic surface, we should consider the influence of the surface drawn by the friction.
The maximum tensile stress along the contact area is: (2) In the formula, u is the coefficient of friction, υis the poisson ratio of the ceramic materials.

DAMAGING OF ULTRASONIC HORN FOR SEMISOLID FEEDSTOCK PRODUCTION Lorenzo Montesano1,a, Annalisa Pola1,b*, Marialaura Tocci1,c, Marcello Gelfi1,d, Giovina Marina La Vecchia1,e 1University of Brescia, Department of Mechanical and Industrial Engineering Brescia, Italy aemail: lorenzo.montesano@unibs.it; *bemail: annalisa.pola@unibs.it; cemail: m.tocci@unibs.it; demail: marcello.gelfi@unibs.it; eemail: marina.lavecchia@unibs.it Keywords: semisolid; ultrasound treatment; ultrasonic horn; TiAlCN coating Abstract.
Some authors replaced the metallic horns with ceramic ones and obtained high chemical stability, good efficiency and superior erosion resistance [22], but also high costs and frequent failures due to the brittleness of the ceramic itself.
An additional cost-effective option aimed at increasing the service life is the use of a metallic sonotrode coated with a thin ceramic layer.
In this paper, the effect of a ceramic thin coating applied on a steel sonotrode for semisolid feedstock preparation was investigated in terms of microstructure modification of the treated alloy.
